Who buys a zidoo mediaplayer above all, does it to watch movies, above all uhd materials cause for 1080p or less a pc works perfectly and you don't need to lose space in your livingroom for other stuff. The performance in this kind of usage is identical for X8 - X9s- X10 - X20 - X20pro but not the price...so what could do the Company Zidoo to encourage customers to spend money for something newest and more expensive? Don't update anymore the cheapest, that is the X8. There isn't another rational answer since with the previous firmware all the Players worked fine and identically. And that was obvious, since they adopt the same chipset or something really really similar (X20 - X20pro). As for me, the X8 works very good. If i have to replace it, i want more and the only best choice for my usage is an oppo 203 (possibly russian firmware to enable the Dolby Vision on usb)
